Safat and Shadman were arrested from Sylhet on May 11. Billal and Rahmat were arrested in Dhaka this week.

The four remanded to police custody have "admitted to committing a lot of what they have been accused of", said Monirul. "We are verifying the information they gave us."
The police had primary information of the crime which was consistent with rape as defined in law, he said.

The remand period granted to police for the four suspects were not finished and the fifth suspect has just been caught, he said. "It will not be appropriate to comment now."

"We have just started questioning the main accused. We have learned that there was sexual intercourse. We'll know what happened after we finish our interrogation," said the top DMP official.

The case involves wealthy suspects and the hotel where the rapes took place is owned by the children of ruling Awami League MP Bazlul Haque Haroon.

The alleged victims mentioned of threats meted out to them by the suspects which caused them to delay notifying the authorities by more than a month.

A probe committee has been formed over their allegations that police initially refused to book their case.

"The law does not recognise powerful men. A criminal is simply a criminal. We'll take action against anyone else related to this incident," said Monirul.
